Catalase (CAT) Activity Assay Kit (E-BC-K031-S)
For research use only.
| Detection Principle | The reaction that catalase (CAT) decomposes H2O2 can be quickly stopped by ammonium molybdate. The residual H2O2 reacts with ammonium molybdate to generate a yellowish complex. CAT activity can be calculated by production of the yellowish complex at 405 nm. |

The recommended dilution factor for different samples is as follows (for reference only):
| Sample Type | Dilution Factor |
|---|---|
| 10% Rat liver tissue homogenization | 25-50 |
| 10% Rat kidney tissue homogenization | 10-25 |
| 10% Rat brain tissue homogenization | 5-10 |
| Human serum | 1 |
| 293T supernatant | 1 |
The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4). For the dilution of other sample types, please do pretest to confirm the dilution factor.
